Problem Booting Disc w/ Knoppix

Good Afternoon,

I'm in charge of administering a program that boots off a CD and runs Knoppix. It is not booting correctly all of sudden and I'm not sure what would of changed. I'm not a programmer or super computer literate. I reached out to the person in charge of solving technical issues with the tests and they informed me the programmer is no longer under contract and couldn't help me. Below is an image of the errors that come up. I've tried booting it on different computers and different connections to the network and still get the same result. Also I have no way of programming it to work, so I'm wondering what hardware or software issues are causing this. It used to work so I don't know what would of changed it.
